The turbo cover upgrade wasn’t a needed modification, but a sort of an impromptu change. I figured it couldn’t hurt anything, besides my wallet slightly.

Collectively we are all learning from each other, which is a major part of posting on this forum.

Thankfully I have lots of passes on the set up and street miles (2k+) so I should be able to sense any difference quickly.

I’ll be adding a back pressure sensor shortly for data collection and understanding where I am with the turbo limit.

My new goal for the car is to get into the 8s. After I get the suspension and cage installed, the turbo will likely be my limiting factor.

Build, race, break(upgrade), repeat ❤️

8.999 @ 3940 lbs (adding 100 lbs for cage) would take over 1000 whp. Not doing to happen with this turbo!

An 88mm tho… 🧐

Didn't you buy the tool to lock the flex plate via the starter bolt holes - to use for tightening the balancer bolt?

How did it work out?

I did purchase, but did not use. When I found the PS pulley was misaligned with the straight edge, I fixed that. I returned the flex plate holder.
